I've changed the fuel solenoid but the injector pump is receiving fuel. I just cant seem to get the fuel to the injectors. May i have some help?

First welcome neighbor.
May I ask a few questions? First brand of tractor? Was it running and stopped? Running rough (skipping or such) or what made you check the fuel system? (It maybe you have
posted that earlier and I missed it.)
To begin with how far in the fuel system are you 100% there is fuel? Are you sure it is reaching the injector pump and then not the injectors is the way I want to read it but that is not stated. If you are not sure there is a free flow of fuel to the injector pump would first do that. If you don't have a free flow then don't over look anything from trash in fuel tank, clooged filter or line.
Okay when I hit reply and the title popped up knew the brand of Tractor. Another question, you have tried bleeding the fuel system, correct?

Hi and thank you for the welcome. New holland TC29 and yes it was running. What happened was the motor ran hot. So I had to replace the head gasket in it. Then once I Got everything back together. I went to bleed the fuel lines and I am getting fuel to the bleeder screw on the pump but not up to the lines. I've checked to see if it had fuel and it did. So Since the pump is built into the block I took the pump off to see if something was broke or stopped up. I blew everything out before I put the pump head back in. I am still not getting any fuel to the injectors. Do you think I need to pull the front timing cover off to see if the spring to the shutoff is broken?
Thank you

Fuel to the pump is one thing, getting it to the injectors is another battle.
Some tractors this isn't much of a problem, some are a bear. The big issue is that a starter only cranks the engine over barely fast enough to start it at the best of times.
There are two solutions;
One is to just barely crack the lines open, one injector at a time, right here they go into the injector. It's messy, time consuming and a little dangerous, the fuel is under tremendous pressure.
The second, and IMHO the way to start is to get the tractor to light up using WD-40 (NOT ether or 'quick-start'!!) down the intake and the engine running will pretty quickly blow the air out of the lines for you.
Best of luck.

Crack open one or two injector supply lines at the injector, crank for about 5 minutes and it should start. I've had to do this more times than I will admit on my 33D

Oh yeah, it will puff white smoke then black and finally start. Shut it off and close the supply lines.

Jeff, 15 seconds of the engine running will do more than that 5 minutes of cranking will.
That's why I suggested starting it, and keeping it running on WD-40 until the air had blown through.
Best of luck.

Murf, a few years back my brother called me to help crank an old gas tractor. Got any starting fluid, no. How about WD 40, HUH? Amazed him.
Does the tractor not have a hand pump for bleeding? That to me is also better than using the starter and if manual transmission there is also the pulling to crank method but if no hand pump would use Murf's recommendation. Much easier if you have someone to spray and someone to crank at same time. Might have to take air filter out, but I have also not had to.

Jeff, today wasn't a waste, you learned something!
Kenny, some of the older tractors had 'primer' pumps on the fuel pump but I doubt they make enough pressure to blow air past the injectors.
They were really only meant to make up for leaky injectors and maybe speed up cold weather starting a little.
Best of luck.
